Ivo, thinking of companies such as Etling, though probably not Sabino,and possible artists:
M Le Verrier, Elie Ottavy, Maurel, F Bazin and Bourdelle, some of which were known to design glass items.
Etling did glass and metal mascots, and according to mascotmania.com, for top-end vehicles. If you visit that, and do the drop down box of glass mascots, the Lalique Perche is there, and looking at the definition on that, and comparing your piece, I think, very little difference in quality of detail.
